NCAR scientist Fei Chen is collaborating with colleagues at China’s Institute of Urban Meteorology to explore how growth in Beijing is changing the city’s summer rainfall patterns, focusing specifically on the relationship between urban expansion, aerosols, and summer rainfall.

A team of scientists has successfully flown from the Arctic to the Antarctic this month, the first step in a three-year project to make the most extensive airborne measurements of carbon dioxide and other greenhouse gases to date.

NCAR postdoctoral researcher Yongku Kim is using epidemiologic data to study the effects of ozone regulation on human health. He’s leading an assessment of how various regulatory standards for ozone may affect non-accidental mortality, including respiratory-related deaths during ozone season.

Wildfires can boost ozone pollution to levels that violate U.S. health standards, a new study concludes.
